Accidents happen. And when they do, it's good to be prepared. One thing I recommend is becoming a Canon CPS member. They have different levels of membership, but the biggest advantage is that you get priority repair turnaround over the average Joe. You also get discount on repair (up to 60% for you accident prone shooters). I always misplace my printed repair forms that Canon sends you. I found one on Google that you can fill out using Acrobat. I thought I'd put it here for everyone and also so I can find it again easily.
